TELEPHONE EQUIPMENT.

7 Application filed August 81, 1925. Serial No. 53,713.

The invention has for an object to present an improvement in equipment for telephone booths and elsewhere, to facilitate the utilization of the telephone. It is a special purpose to offernew devices to automatically close circuits suitable for lighting and indicating occupancy of booths, and also toproride for special illumination when required, as for writing; while at the same timeinsun ing proper setting of circuits in initial positions when a booth is vacated. It is also an aim to add conveniences to telephone supports for the benefit of users generally in various situations.

It is a specific object to embody a novel and desirable form of mechanism actuated by movement of the receiver hook to control lighting circuits, and which will provide for movement of the receiverhook without disturbing these circuits if necessary as, when it is required to attract attention of a telephone central operator by producing signal impulses in the telephone circuit. A further object is to provide a novel device cooperatively associated with the last mentioned apparatus and circuits whereby departure of a patron from the telephone will place the circuits in initial condition, so as to remain indepenc'lentlyof any further movements of the door, until a patron again desires to make use of the equipment.

Additional objects, advantages and features of invention reside in the specific construction, the combination and the arrangement of parts, as Wlll be more readily understood from the following description and accompanying drawings of one embodiment of the invention, wherein,

V Figure 1 is a top View of a telephone installation in accordance with my invention.

Figure 5 is a wiring diagram of-th-e equip ment.

Figure 6 is a diagrammatic illustration of a telephone installation with one type of booth.

Fig. 7 is an elevation of a closedbooth.

There is illustrated a table element 10, which may be a shelf or the top of any structure of suitable height It is formed with a central opening 11 over which there is set receiver 16 may be laid.

' gitudinal'ly extensible.

. switch the base 12 ofthe usual telephone transmitter 13, which includes the mouthpiece l4 and vertically oscillatable, resiliently supported, receiver hook or telephone switch 15. A

telephonic receiver 16 is also illustrated, of

a familiar type such as is ordinarily held to the ear by one hand andthis is hung in the usual way on the hook when the telephone is not in use. The specific details of the telephone circuits and switch may be of the common form and comprise no novel part of larly extended a flexible .arm 26, means 27 being tions.

Pivoted on, the arm 26 at its extremity- Wlth a ball and socket joint 28 there is a second rigid arm 29; the ball and socket joint being of a typev including a clamping screw 30 by means of which the arm 29 may be universally adjusted and secured at various positions on its pivot. At the outer end of the arm 29 there are two furcations 3l the outer partsof which are bowed downwardly as at 32 forming together a rest in which the Medially between and above the furcations there is a resilient retainer spring 33 having a shape similar to that of the furcations 31. The extremities of the furcations and spring are divergent so that a receiver may be laid against these divergent parts and by. pressure at the outer provided to secure it in extended posiside forced between thespring and the furcations. If desired, the armc29 may be lon- Rearwardly offhe receiver 13 there is a panel 32, upon which there is mounted a simple switch 33 including a pivot arm 34 operable by vertical movement, a link 35 being connected thereto extending downwardly to the intermediate part of the hook arm 15, to which'it' is pivotally connected so that the switch will be operated by movement of the hook 15.- The switch includes upper and lower contacts 36-37,

and'serves to close on the lower contact a a circuit 38 to a whitelight 39 at a distant point toindicate that the telephone is not .tance an equalizer bar 52 is connected in use, while on the upper contact it closes a circuit to a red light. 41 in the same situation and also the white light 21 beto-re mentioned on the standard 20.

()n the panel 32 there are also located wall switch-es d2 and a3, one adapted to close a :ircuit 44 to the lights i1 and- 21 as mentioned and the other, adapted to close a c-ircuit 15 to the light 28 before mentioned for illuminating the writing shell, as indicated in the diagram in l i ui'e 5, wherein a battery 16 is formally indicated as the source for energizing the circuits.

The switches 2'.-&3 are of the familiar snap, lever, type, and means is provided to insure extinguishing ofthe lights 2i28- ll when a patron leaves a telephone booth leaves the telephone. t is considered ui'idesirable merelyito break the circuits to the lights independently of the switches e2 4?) which would impair the utility of these devices, and therefore the means of a character to return these switches to initial oii position.

Each of the levers of the switches 1 43 have connected thereto draft links 51 extending backwardly from the switch and attached to the ends which are to be moved inward to'ofliposition, and at suitable disacross these links. From the middle o't the bar a draft connection 53 including a slightly resilient element 54 is extended to a'lever 55 located adjacent thedoor or other hinged elementtio by which patrons gain access to the telephone. This element 56 has a wiper efhavi'ng a dog 58 on the end adapted to yield to the lever 55 when the element 56 is moved to closed position, and upon movement of the element 561:0- open position will oositivel en 'a 'e and .move the lever 55 so in b as to move it for resetting of the switches 4C2 l3, as may be understood. In case the switches arealready in initial or off positionth e lever 55 will not be operated but will be then held in opera-ted position-by the switches lO lLunl-ess some alternative connections are employed.

Pivoted on the panel 32 also there is a means to operate thehook 15 without disturbing the light circuits in case it is desired to attract the attention of a central operator. This consists of ahand lever 60 pivoted intermediately of its length with a lower end disposed conveniently to be grasped together with the column of the transmitter 13 so that by ti ghtening the'grip upon the two the lever will be operated, the transmitter serving to give the patron a'.

purchase by which the lever may be operated with a minimum effort. A spring-61 is provided to hold the lever yieldingly in initial position.

A second lever or switch arm 62 is pivoted at one end on the panel 32 having an initial operative position with its. opposite or swinging vendextended upwardly. a little toward the transmitter or lever 60. Stops 63 are provided tp, limit movement of the arm (32,"and a contact 6% is located to'be engaged by the arm when operated from initialposition, to close a circuit to the lights l-l andg21. A link 65 is connected to the upper end of the lever 60 and mutually pivotedon the inner ends of toggle links 66. the outer end of one of which is connected-to the upper endof the switch arm 62. and the outer endot the other connected to the outerpart of the hook 15, The parts are so arranged relatively that. when the switch arm 62 is in operated position through operation of the hand lever 60, the links 66 are extended in an oblique relation betweenthe hook 15 and the arm 62, and when the lever 60 is releasedit'operates through the link 65 to draw the leversfifi toward the rightf rst permitting the hook to rise, and then drawing thearin 62 to initial oropen circuit position against the stop.

twill be seen that in the use of any appliance a patron may ascertain from a distance whetherany oneelse is using theph-one or is in the booth therewith, by reason of the illumination oflthe red light displayed, and ifthe phone is not engaged byany one a white lightwillgbe displayed. This is especially, useful in large public stations where banks of booths are provided, and is also desirable-even when but a single phone installationis provided, to avoidlawkward situations between patrons.

lVhen the receiver is removed from the hook the movement of the latter will automatically. change the distant signal from white to red atthe same time thatthe interior of, the booth is illuminated, or, if the patron desires first to search a name in the directoryhe will preSS. abutton of a wallswitch provided "for the purpose, which will cause display otthered distant signal and illuminate the booth byflthe same lights involved in operation of the hook 15.

7 It is an advantage of my appliance that in case any one operates the door .or ot-her device 56 while a patron isiusing thetelephone it will notextinguish the distant signal nor the booth illumination but will leave these in a condition-to be automatically restoredv to initial condition, when the receiver is hung up.

It will be seen that the appliances involved are of asimple character adapted tobe produced readily at alow cost, and that theyare of a durable character and liable in a minimum degree to derangement; as well as installations. As indicated in Figure 6, in case thetelephone is not enclosed in a booth, a chair 70 may be provided w th a swingbeingapplicable to many various types of i ing arm 56 which will require to be operated by a patron in leaving the seat, which will insure the functions of restoring circuits to initial position after manipulation of the switches.

1: means operatively associated therewith to reset the last named switch in initial position when said closure is opened.

2. In telephone equipment, a telephone circuit switch, a light circuit controlled thereby, a second light circuit, a manually operable switch to control the light circuits, a booth closure and means operatively associated therewith to reset the last named switch in initial position when said closure is opened.

3. In telephone equipment, a telephone circuit switch, a light circuit switch connected positively therewith,a third switch and operating means therefor having a lost motion connection with the telephone circuit switch, and a light circuit controlled by the second and third named switches.

4. The combination of a reciprocatable member, a light circuit, a switch therefor,

operative connections between the recipro- I catable member and the switch, a second switch connected to separately close the light circuit at times when the first named switch is open with respect to said circuit, a lever operatively connected with the second switch and operative connections between the lever and reciprocatable member constructed to close the second switch during movement of the reciprocatable member over a predetermined part of its path.

5. The structure of claim 4 in which the first named switch is operatively associated with a second light circuit in a relation to close the same when the switch is in open relation to the first named light circuit.

In testimony whereof I afiix my signature.
